Epiphan Pearl - Manual (Page 7)

l
Due to changes in the way channel layouts are created, some HTTP and RS-232 remote layout
commands no longer available 3.15.1 and 3.15.2. These include values for setting the text overlay,
logo, logo positioning, keep aspect ratio and no signal image.
Workaround: Update your scripts to avoid using these commands. See the manual for a full list,
affected API keys are listed as deprecated.
l
Custom No Signal images are not available in 3.15.2.
Workaround: If possible in your application, use layouts to create a full-screen image that depicts the
desired no signal message and switch to the live feed when it comes online. Otherwise, use the default
no signal image.
l
Text overlays in 3.15.2 do not support the %c variable to show the channel name.
Workaround: If channel name is desired in the text overlay, type in the name manually into text
overlay box in the layout editor.
l
When using Internet Explorer to view the web admin interface, cached versions of pages can be
displayed instead of the most recent version of a page. This affects the Sources configuration page
most and may cause the user to think a new layout or changed layout has gone missing.
Workaround: Refresh the page by pressing Ctrl-F5.
